The purpose and functional characteristics of dynamic compression shear testing machine

The dynamic compression shear testing machine is a high-tech and high-precision material mechanics testing equipment, mainly used to simulate and test the comprehensive mechanical properties of materials or structural components under continuous pressure and lateral (shear direction) reciprocating dynamic loads. It is a key equipment for evaluating the fatigue life, durability, and seismic performance of products.

1. Main purpose

This device is mainly used to simulate the dynamic fatigue performance of structural components (such as building isolation bearings, bridge bearings, seismic components, seismic elements, etc.) under the combined action of pressure and shear forces in actual work.

Typical test objects include:

Building isolation rubber bearings

Basin type support, plate type support

Seismic ball joint bearing

Various types of shock absorbers and damping devices

Other composite materials or components that need to withstand both pressure and shear forces simultaneously.

2. Core functions and features

Composite loading: capable of simultaneously applying axial pressure (vertical direction) and horizontal shear force to the specimen, simulating the actual stress state.

Dynamic fatigue testing: It can perform tens of thousands or even millions of reciprocating loads at a certain frequency and amplitude to test the fatigue life, stiffness degradation, energy dissipation capacity, etc. of the test specimen.

Static performance testing: It usually also has static testing function, which can test parameters such as compressive shear ultimate bearing capacity, yield strength, shear modulus, etc.

Multi channel control: An advanced electro-hydraulic servo control system that can independently or collaboratively control vertical and horizontal actuators to achieve complex loading waveforms (such as sine waves, square waves, triangular waves, or custom waveforms).

High precision measurement: equipped with high-precision force sensors, displacement sensors, and deformation measurement devices to ensure the accuracy of data collection.

Software system: equipped with professional measurement and control software for setting test parameters, displaying load displacement curves in real time, automatically recording data, and generating test reports.
